Penny in my block

[Ross F-1]

I just put my engine back together, using a Canadian aluminum intake. I used .010 SS shims over the risers, on top of the gasket. With temps in the mid-60's, it takes a solid 5 minutes before I can get off the choke and drive. The carb is ice cold! Going to pull the shims and drill about 5/16" holes in them, try that.

I welded the intake hold off

You can always remove the intake manifold to install the pennys. Another Barn member told me to use .025 metal stock and cut out small tabs 1 1/4" X 1 1/2 " then bend a tab at the end to help with the installation. Loosen the intake manifold bolts, put grease on both sides of the tabs and slide them in under the manifold and on top of the gasket, then retighten the bolts. That way if you don’t like the sound or for any other reason you can just loosen the bolts and slide it out. The only drawback is in the winter the car will run like crap until the block heats up.


My logic would be: as to the pennies, I am not sure they are legal tender, and if they are in your block or manifold they are out of circulation.

One other point, is that during the summer it drops the temp of the carb, eliminating the "vapor lock" issue.


Hope the pictures answer your questions as to the location of the heat riser and where the block off tabs or the pennys go. I will tell you the sound is great!!!!!
